Abstract

Laboratory soil analysis is one of the effective way of knowing the nutrient content of the soil. However, it is expensive and difficult to avail from the government facilities for free laboratory soil analysis. Minus one element technique (MOET) is a friendly and less expensive way of knowing the nutrient status of the soil. This study aimed to determine the nutrient status of the lowland soil in Central Luzon State University (CLSU) rice farm. Minus one element technique (MOET) was used through observation of growing rice (NSIC Rc216) variety planted in a container. The fertilizer formulations considered as the treatments included the following without nitrogen (-N), without phosphorus (-P), without potassium (-K), without sulfur (-S), without copper (-Cu), and without zinc (-Zn). Rice plants receiving complete nutrient elements served as the control. Results revealed that no visible deficiency symptoms in the growing rice except on minus nitrogen and minus sulfur treatments. This result suggested that the soil in CLSU rice farms still have sufficient nutrient elements except on nitrogen and sulfur. Plants in minus N element showed yellowing of the leaves starting at the older leaves and moves along to the middle leaves two weeks after planting. This treatment show less number of tillers and foliage as compared to the treatment receiving complete nutrients. Plants in minus sulfur appears a pale green to pale yellow leaves starting in the younger leaves. Thus, soil in CLSU rice farm needs Nitrogen and Sulfur nutrient elements and need to be addressed.
